'I'his invention relates to bezel mountings, and provides particularly a bezel mounting of floating character adapted forarrangement at an opening in alwall, and which Will permit dis- .crepancies in the opening.

The preferred form of the; present invention is adapted to be mounted on an ordinary type of domestic gas range or oven. The bezelgis secured to the Wall or panel of the oven, `and del0 flne's a mounting, or opening, through which the selecting' mechanism `of an oven heat regulator or thermostat is adapted to extend for manipulation by the operator.

' I preferably ,'provide the bezel or mountingv ring 15 with an internal diameter slightly larger than the external overall diameter of the selectingA mechanism. This facilitates removal of the panel or oven wall to permit access to certain parts of the heatregulator or internal oven chamber, without removing any of the parts ofthe selecting mechanism. Also, the difference inv diameters of the mounting ring and the selecting mechanism insures that the selecting mechanism will be properly positioned regardless of variations in range l` manufacture,

, Another feature of the present invention resides in providing the mounting ring with an inwardly extending cylindrical portion of less external diameter than the diameter of the cutout aperture in the oven wall or panel, thus permitting accommodation of the mounting ring inA a plurality of positions with respect to the panel, and allowing for discrepancies in the form and positioning f the opening. The necessity of accurately or precisely forming and positioning the aperture in the panel or oven wall is eliminated andv a mounting of what I term a floating character is provided, namely, a mounting-that is adapted to .be positioned concentrically with the selecting mechanism or other device regardless of the precision with which-the hole in the oven wall' 'or panel is formed.- It is thus apparent .that the bezel has a relatively floating engagement with the panel, `and can be accurately alined with respect to the selecting mechanism. The inwardly extending portion of the bezel may be provided with slots adapted to receive inwardly extending ears of a cup-shaped retaining ring, or may be provided with depressions, which cooperate with suitable grooves formed in the housing of the oven heat regulator to prevent .rotation of the bezel -about the selecting -mechanism. j

In connection with this feature, the floating bezel of the present invention is adapted to be 1932, seal No. 599,691

used either with, a housing which has a flanged portion of. substantiallyA the same diameter as the mounting ring, or may be used with an oven heat regulator housing having only a projecting stud portion for mounting the retaining ring. l

embodiment, the bezel retaining ring is of cup. jformation, and is locked against rotation upon' the oven heat regulation housing, and the mounting ring is .snappedjinto engagement therewith and securely heldin position with respect thereto.

Further features and advantages of my inven- -tion will appear more fully in the following detailed description, which, taken in connection with the accompanyingfdrawing, will disclose to those'skilled in the art-.the particular construc- -tion and operation of certain ments of my present invention.

preferred embodisectional view of a modied Referring now in more detail to the drawing,

in the embodiment disclosed in Figs. l and 2, the oven wall or panel is indicated by the reference numeral 5. 'I'his oven wall or panel may be the front wall of the oven; or maybe a side Wall of the oven, orany other wall upon which it is desired to mount the selecting mechanism for controlling the oven heat regulator.

The wall 5 is provided with a cut-out aperture or opening 6, through which the selecting mechu anism, indicated by the reference numerall, is l, adapted to extend. This aperture 6 is of gen- V quired in forming this-aperture, and. it e formed by merely stamping the desired opening in the oven wall 5. l v i The selecting mechanism, indicated at 1, comprises the dial member 9, and the control knob I which are concentrically mounted upon the control vspindle II. A pair of friction washers engage the dial member for securing it in nonrotating engagement with respect to the spindle II, and a screw I2 secures the control knob III upon the spindle in abutting relationship with respect to the washers and the dial member so .flange I5' of the cup-shaped member.

as to form a compact construction in which `the parts are bound together to rotate as a unit. The control spindle II threads into a suitable housing. I3, which housing has a projecting 'hub portion, I4 for receiving the retaining member I5y of the -bezel mounting.

This `retaining member I5 is of cup-shaped form, and is provided with a central opening It;k having the slabbed off 'edges I'I and I8 cooperating with similar surfaces formed on the projecting hub portion I4 to secure this member in nonrotativev engagement with the housing. A suitable spring I9 is provided between the base of the cup-shaped retaining member I5 and the washer 20 which washer 20 bears against the collar 20 of the control spindle. The spring I9 biases the member I5 about the projecting portion I4 of the housing. This 4serves to position the member I5 resiliently upon the housing.

The control spindle II extends through the housing/,and has the projecting stud portion 2I `shaped member' I5 4at 22. This tongue 22 is adapted to extend outwardly into the plane of the dial member 9, which dial member is provided with an inwardly extendingpintadapted to contact against the tongue 22 for limiting the rotation of the dial member. l

Referring now in more detail to ,they bezel mounting, the retaining member I5 is provided .with a pair of inwardly projecting diametrically opposite protuberances or ear members 24 which may be pressed out of the cylindrical upstan'ding These ears or lugs. are adapted yto engage in suitable bayonet slots 25 formed in the'inwardly extending cylindrical flange portion 8 of -the bezel or mounting member 8. It will be noted that-each of the slots is provided with a recessed portion 25 in which the ears 24 are adapted to engage when the bezel mounting is `properly positioned.

In assembling the selecting mechanism and associated bezel mounting, the housing I3`is first placed in position, and the member I5 secured thereon. The mounting member 8 is then po-` sitioned upon the oven wall `5 with the cylindrical flange part 8' ertending through the' opening 9 and in position to telescope into the cylindricalflange I5 of the member I5. Thus,yby pressing` the mountingmember 8' inwardly, theV ears 24 being first registered with the open ends of the slots 25, 'these ears 24 are -engaged in the slots 25 andkb'y rotating the mounting member 3 the ears 24 are brought into engagement-with the vrecessed portions 26 of the slots with the flange 's' telescopes into and held in the na'hge 15'-, The

housing 2|, the spring I9, `the dial member 9 and the control knob Il) positioned thereon, and the f device is adapted for operation. It will be noted that the spring I9 forces ,the member I5 rearwardly and serves' to tension this member with respect to the mounting ring 8, thus holding the mounting ring in rm, non-rotative engagement.

The radial flange 60 is held yieldingly and flrmly against the outer side of the oven wall 5 and covers the adjacent margin of the opening 5, and an annular outwardly bulged connecting part 80 connects the radial flange 60 with the cylindrical flange 8'of the mounting member.

Referring to the modified form shown in\Fig ure 3, this differs from the embodiment of Figures 1 and 2 in that the member I5, corresponding to pressed inwardly when the member 8 is engaged i with the member I5 and released therefrom. In the previous embodiment this yield may likewise be in the oven wall although inthat case the spring I9 permits the member I5 to be pressed toward the member 8 for this purpose. In each case this facilitates the locking of thesetwo members together, and also assures that they will be maintained yieldingly yet rmly in relative position. 1 If desired, the oven wall 5 may be removed without removing the selecting mechanism 'I, by merely disengaging the slots 25 from the ears 24, and removing the wall outwardly past the selecting mechanism. This facilitates `access to the interior of the oven without interfering with the setting of the control selectingfmechanism. Y

Referring now in more detail to Figures 4 and 5, the embodiment disclosed therein is adapted to f ofthe oven wall. In devices ofl this type. thel mounting member is so constructed as to fit around the housing and is keyed thereto in' uch `l manner as to prevent rotation of the bezel mo t- Considering the structure in more detail, I have disclosed the o ven wall 30, which is apertured, as

at-3I, to provide for the disposition of the select-1 ing mechanism indicated generally by the reference numeral 32 at the upper portion of the heat regulator housing 33. This selecting mechanism 32 is substantially thesame as disclosed'in conjnection with FigureV i, and needs no detailed de'- mally sensitive member 35. Rotation of/` the spindle 34 serves to control the position of themember 35 for regulating the valve or other con- `trol rchanism supplying fuel to the oven burn,- er. `e

housing 33 has the extending, ilang'eriiportion 36, which is disposed substantially in the plane of the oven wall 30, and which is provided at its-upper and lower edge's with suitable diametrically opposite grooves 31 which are adapted to receive the depending ear portions 39 of the bezel mounting ring 39.

Thisbezel mounting ring 39 is substantially of the same form as the' ring or bezel member 8 of Figures 1 and 2, and is provided with the radially iianged portion 40 adapted to have abutting engagement with the outer surface of the oven wall 30. The inner extending cylindrical portion 4I extends within the oven and is secured about the flange 36 to dispose the member 39 in nonrotat-4 ing engagement therewith. The internal diameter of the cylindrical flange of the member 40 is slightly larger than the external diameter of the selecting mechanism 32, and the oven wall may be removed without disturbing the setting of the selecting mechanism.

The cylindrical iiange portion 4i of the member 39 is provided with a pair of rectangular slots 42, which engage with suitable ears 43 struck inwardly from the inner periphery of the retaining ring member 44. 'I'his retaining ring member 44 is of substantially annular shape, and is provided with a plurality f spring tongues 45 struck out of the radial surface thereof, these spring tongues 45 bearing against the inner surface of the oven wall 30, and serving to resiliently engage therewith for the purpose of permitting' the mem# ber 44 to be pressed over the extending portion 4| of the'bezel member 39 until the ears 43 there of engage in the slots 42 in this member. This engagement serves to lock the retaining ring `44 -to the member 39, and thus serves to position positively the member 39 with respect to the oven oven wall, and in the stamping of the aperture for receiving the selecting mechanism, maybe permitted and accommodated.
